650 bool "kexec system call (EXPERIMENTAL)"
651 depends on SUPERH32 && EXPERIMENTAL && MMU
653 kexec is a system call that implements the ability to shutdown your
654 current kernel, and to start another kernel. It is like a reboot
655 but it is independent of the system firmware. And like a reboot
656 you can start any kernel with it, not just Linux.
658 The name comes from the similarity to the exec system call.
660 It is an ongoing process to be certain the hardware in a machine
661 is properly shutdown, so do not be surprised if this code does not
662 initially work for you. It may help to enable device hotplugging
663 support. As of this writing the exact hardware interface is
664 strongly in flux, so no good recommendation can be made.
667 bool "kernel crash dumps (EXPERIMENTAL)"
668 depends on SUPERH32 && EXPERIMENTAL && BROKEN_ON_SMP
670 Generate crash dump after being started by kexec.
671 This should be normally only set in special crash dump kernels
672 which are loaded in the main kernel with kexec-tools into
673 a specially reserved region and then later executed after
674 a crash by kdump/kexec. The crash dump kernel must be compiled
675 to a memory address not used by the main kernel using
678 For more details see Documentation/kdump/kdump.txt

687 config PHYSICAL_START
688 hex "Physical address where the kernel is loaded" if (EXPERT || CRASH_DUMP)
691 This gives the physical address where the kernel is loaded
692 and is ordinarily the same as MEMORY_START.
694 Different values are primarily used in the case of kexec on panic
695 where the fail safe kernel needs to run at a different address
696 than the panic-ed kernel.
699 bool "Enable seccomp to safely compute untrusted bytecode"
702 This kernel feature is useful for number crunching applications
703 that may need to compute untrusted bytecode during their
704 execution. By using pipes or other transports made available to
705 the process as file descriptors supporting the read/write
706 syscalls, it's possible to isolate those applications in
707 their own address space using seccomp. Once seccomp is
708 enabled via prctl, it cannot be disabled and the task is only
709 allowed to execute a few safe syscalls defined by each seccomp
714 config CC_STACKPROTECTOR
715 bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
716 depends on SUPERH32 && EXPERIMENTAL
718 This option turns on the -fstack-protector GCC feature. This
719 feature puts, at the beginning of functions, a canary value on
720 the stack just before the return address, and validates
721 the value just before actually returning. Stack based buffer
722 overflows (that need to overwrite this return address) now also
723 overwrite the canary, which gets detected and the attack is then
724 neutralized via a kernel panic.
726 This feature requires gcc version 4.2 or above.
729 bool "Symmetric multi-processing support"
730 depends on SYS_SUPPORTS_SMP
731 select USE_GENERIC_SMP_HELPERS
733 This enables support for systems with more than one CPU. If you have
734 a system with only one CPU, like most personal computers, say N. If
735 you have a system with more than one CPU, say Y.
737 If you say N here, the kernel will run on single and multiprocessor
738 machines, but will use only one CPU of a multiprocessor machine. If
739 you say Y here, the kernel will run on many, but not all,
740 singleprocessor machines. On a singleprocessor machine, the kernel
741 will run faster if you say N here.
743 People using multiprocessor machines who say Y here should also say
744 Y to "Enhanced Real Time Clock Support", below.
746 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
747 available at <http://www.tldp.org/docs.html#howto>.
749 If you don't know what to do here, say N.
752 int "Maximum number of CPUs (2-32)"
755 default "4" if CPU_SUBTYPE_SHX3
758 This allows you to specify the maximum number of CPUs which this
759 kernel will support. The maximum supported value is 32 and the
760 minimum value which makes sense is 2.
762 This is purely to save memory - each supported CPU adds
763 approximately eight kilobytes to the kernel image.
766 bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"
767 depends on SMP && HOTPLUG && EXPERIMENTAL

770 can be controlled through /sys/devices/system/cpu.
772 source "kernel/Kconfig.preempt"

778 This enables support for gUSA (general UserSpace Atomicity).
779 This is the default implementation for both UP and non-ll/sc
780 CPUs, and is used by the libc, amongst others.
782 For additional information, design information can be found
783 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
785 This should only be disabled for special cases where alternate
786 atomicity implementations exist.
789 bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
790 depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
792 Enabling this option will allow the kernel to implement some
793 atomic operations using a software implementation of load-locked/
794 store-conditional (LLSC). On machines which do not have hardware
795 LLSC, this should be more efficient than the other alternative of
796 disabling interrupts around the atomic sequence.

850 kernel image to an MMC card and boot the kernel straight from
